EMG (Electromyogram)Â is employed as a diagnostic tool to identify neuromuscular conditions, evaluate lower back pain, study kinesiology, and investigate motor control disorders. Additionally, EMG signals serve as control inputs for prosthetic devices, including prosthetic hands, arms, and lower limbs.
AÂ nerve conduction velocity test (NCV)Â is an electrical examination utilized to determine the efficacy of nerve impulse conduction along a nerve pathway. This assessment is valuable in identifying authentic nerve disorders (such as peripheral neuropathy and mononeuritis multiplex), as well as situations where nerve function is compromised due to mechanical compression injuries (like carpal tunnel syndrome and other compression neuropathies).
Nerves carry signals from the brain to the muscles and Nerves controls the action of the muscles by electrical signals, called impulses, that measures your nerve signalling and muscle response. Specifically, the needle EMG measures the electrical activity of your muscles. The aim of the EMG is to identify and determine the location, source of the problem.
